Definitions
- MOF Metal-Organic Framework
- This invention relates to metal organic framework (MOF) compositions which have at least one linker molecule with an aryl amino group.
- the MOF has also been post-synthesis treated with a metal salt solution.
- This invention further relates to a process for preparing and activating the modified MOF compositions, as well as a process for using the MOF compositions to remove either basic or acidic toxic industrial compounds (TIC) from a gas stream.
- TIC acidic toxic industrial compounds
- Adsorbent materials are well known and have found uses in a number of applications such as air filtration, gas delivery, etc.
- One particular use for adsorbents is in removing or abating contaminants in various gas streams and in particular removing Toxic Industrial Compounds (TIC) present in air streams.
- TICs can be classified as either basic or base forming compounds or acidic or acid forming compounds.
- an adsorbent will exhibit adsorption capacity for various TICs. But the capacity for each TIC is dependent on the properties of the adsorbent, resulting in materials that often perform well at adsorbing one TIC but not multiple TICs.
- the MOF adsorbent Zr(NH2-BDC) has been shown to have good adsorption capacity for NO2 but modest capacity for ammonia. Filters that must abate multiple TICs are routinely required in a wide range of industries. These technologies typically utilize multiple adsorbents. That is, the capacity for one TIC may be sufficient to abate a target TIC in a particular gas stream, but not high enough to abate another TIC in the same gas stream. This necessitates the use of multiple adsorbents in order to abate two or more TICs in a gas stream such as air. Therefore, there is a need for an adsorbent material that can adequately remove or abate two or more TICs. We describe herein a class of adsorbent materials capable of removing multiple TICs from a gas stream with high capacity. More specifically, there is a need for a MOF which can abate both basic and acidic TICs.
- Applicants have developed a class of modified MOF materials which have enhanced adsorption capacity for basic compounds such as ammonia while maintaining good adsorption capacity for acidic compounds such as nitrogen dioxide or chlorine.
- the surprising aspect of the invention is that the adsorption capacity for the acidic gases is not substantially decreased when the MOF is modified so that it has enhanced adsorption capacity for basic compounds versus the unmodified MOF.
- the MOF materials which can adsorb both acidic and basic gaseous compounds are prepared by taking a synthesized MOF with good adsorption properties for acidic compounds and impregnating it with a metal salt solution, followed by activation.
- MOFs such as UiO-66 can be impregnated with a metal compound such as a metal hydroxide or metal hydride to disperse the metallic compound either on the surface or in the pores of the MOF.
- a metal compound such as a metal hydroxide or metal hydride
- CWA chemical warfare agents

Once the paste-like material is formed it can be extruded through a die having holes of about 1-4 mm to form extrudates of varying length, e.g. 2-50 mm. The paste or even the powder itself can be pressed at high pressure to form pellets or pills. Other means of forming shapes include pressure molding, metal forming, pelletizing, granulation, extrusion, rolling methods and marumerizing.
- the metal-impregnated MOF materials can be deposited onto articles such as, but not limited to, monoliths, spherical supports, ceramic foams, glass fibers, woven fabrics, nonwoven fabrics, membranes, pellets, extrudates, irregularly shaped particles, and mixtures thereof.
- articles such as, but not limited to, monoliths, spherical supports, ceramic foams, glass fibers, woven fabrics, nonwoven fabrics, membranes, pellets, extrudates, irregularly shaped particles, and mixtures thereof.
- a slurry of the MOF composition is prepared and deposited on the article by means such as dipping, spray drying, etc. followed by drying and optionally calcination.
- For membranes it is possible to form the modified MOF composition directly on the membrane.
- the metal-impregnated MOF compositions of the invention can be deposited or dispersed onto fabrics (woven and non-woven) or polymers by techniques such as electro-spinning, direct crystal growth, and layer by layer deposition.
- the metal-impregnated MOF containing articles described in the previous paragraphs can be used as is to purify air or other gas streams containing contaminants.
- the air or other gas streams can be flowed through the article, e.g. monolith, foam, membranes, fabrics whereby the metal-impregnated MOF will adsorb at least a portion of the at least one contaminant.
- the metal- impregnated MOF articles can also be placed in various types of rigid containers. For example, extrudates or pills or spheres can be housed in a bed through which the air or other gas stream is flowed through.
- the bed can be placed in various types of housings such as filter canisters having an inlet and outlet.
- Fabrics can also be formed into filters such as but not limited to pleated filters which again can be housed in rigid containers such as cartridges through which the stream to be treated flows through.
- the cartridges are part of a face mask.
- Pleated filters can also be supported in various shaped and sized frames and the gas stream flowed through it.
- the frames can be made of various types of materials such as but not limited to metal, wood and plastic.
- Fiber glass can be formed into glass wool and housed in rigid filter frames.
- the metal-impregnated MOF can be used in an apparatus comprising at least one impregnated MOF composition as disclosed herein.
- the apparatus further comprises an adsorbent other than an impregnated MOF composition as disclosed herein.
- the other adsorbent is a MOF composition that is not metal-impregnated.
- the other adsorbent is a zeolite.
- the other adsorbent is an activated carbon.
- the apparatus comprises a mixture of at least one impregnated MOF composition as disclosed herein and another adsorbent.
- the apparatus comprises a layer comprising at least one impregnated MOF composition as disclosed herein and at least one layer comprising another adsorbent.
- an apparatus comprises an assembly or apparatus which comprises a plurality of layers or a non- layered mixture of particles through which a gas stream, e.g. air stream is flowed.
- the first layer which contacts the gas stream is the metal-impregnated MOF layer
- the second layer contains another adsorbent such as activated carbon, zeolites, or other known adsorbent.
- the gas stream can first contact a layer that contains another adsorbent, and then a layer that contains the modified MOF.
- Additional layers may be added as needed, for example a hopcalite layer.
- layers of two different metal- impregnated MOFs can be used, or layers of a metal-impregnated MOF and a non-impregnated MOF.
- two or more modified MOFs can be mixed and form one layer, or a layer can comprise a metal-impregnated MOF and a non-impregnated MOF.
- These layers can be arranged in a bed which can be housed in a rigid structure such as a canister, e.g. or a larger vessel if a large gas stream is to be purified, e.g. air stream entering a commercial building.
- the metal-impregnated MOF in the layer can be in the form of a powder or any of the shapes and forms described above.
- Activated carbons which can be used as another adsorbent as described above are highly porous, high surface area adsorptive materials with a largely amorphous structure. They are composed primarily of aromatic configurations of carbon atoms joined by random cross- linkages. The degree of order varies based on the starting raw material and thermal history. Graphitic platelets in steam-activated coal are somewhat ordered, while more amorphous aromatic structures are found in chemically activated wood. Randomized bonding creates a highly porous structure with numerous cracks, crevices and voids between the carbon layers. Activated carbons may be in the form of powder (PAC), granule (GAC) or extrudate (EAC). All three forms are available in a range of particle sizes.
- PAC powder
- GAC granule
- EAC extrudate
- the modified MOFs and activated carbon or other adsorbent are deposited on fabrics (woven or nonwoven), the fabrics can be arranged as layers of a face mask.
- a pleated sheet can be formed which comprises layers of activated carbon or another adsorbent and metal -impregnated MOFs.
- the pleated sheets can be formed into various arrangements such as filter canisters or be housed in a rigid container such as a frame which can be made of various materials such as plastic, wood, metal, cardboard, etc.
- Zr (BDC-NFb) also known as UiO-66-NFb was prepared using literature procedures. Generally, the procedure involved dissolving the NFb-BDC ligand in a solvent such as DMF (dimethyl formamide), then adding formic acid, followed by heating the solution to a temperature of about 90°C, adding Zr0(N03) and reacted for a time to provide the MOF. The MOF powder was isolated, washed with DMF and acetone, washed with hydrochloric acid, and dried at a temperature of about 100°C for a time of about 12 hours.
- a solvent such as DMF (dimethyl formamide)
- Zr(NTb-BDC) was prepared per the procedure of Example 1, except that the MOF was dried at 80°C to achieve a hydration level of 10-15% water.
- To a pan mixer 1948g of Zr(BDC- NFb) were added along with 3 wt. % PVP and the mixture thoroughly mixed.
- a mixture of diluted MgCb solution was prepared using 328mL of saturated MgCb solution diluted to the approximate pore volume of the MOF. This was added to the mixture. This new mixture was continued to be mixed until granules formed. The granules were sieved and the desired size granules were dried at 100°C under vacuum until a dynamic pressure ( ⁇ 0. ITorr) was reached.
- Zr(NFb-BDC) was prepared per the procedure of Example 1.
- the material was blended in a pan mixture with a colloidal silica solution to make a compactable mixture.
- the material was roll compacted and ground to the desired size.
- the material was then soaked for about 20 hrs in a ZnCb/acetone solution at a concentration selected to provide the desired zinc loading on the final MOF product. After soaking the material was allowed to air dry, then subjected to another coating with the same colloidal silica solution. This material was air dried, then dried at 100°C under vacuum until a dynamic pressure ( ⁇ 0. ITorr) was reached.
- Ch uptake was measured as follows. CI2 gas was injected into a mixing ballast and subsequently pressurized to yield a concentration of 10,000 mg/m 3 . The ballast contents were then mixed with a diluent air stream under dry conditions to achieve a challenge concentration of 2,000 mg/m 3 . The mixed stream then passed through a sorbent bed submerged in a temperature- controlled water bath at 20 °C. Approximately 50 mm 3 of each sample was packed into a 4 mm i.d. tube, corresponding to 4 mm of bed depth and a residence time of approximately 0.15 s.
- Table 2 shows that a Zr(NH2-BDC)which has been impregnated with either nickel chloride or magnesium chloride retains the adsorption capacity of the non-impregnated MOF for chlorine (an acidic TIC). This is an unexpected result since the same metal-impregnated MOFs have increased ammonia adsorption (see Table 1). The ability of a MOF to adsorb considerable quantities of both basic and acidic TICs has not been observed previously.
